Part Number: TMS320C6745
Tool/software: Code Composer Studio
I'm using TMS320C6745 for my project of speech quality evaluation of 4 channels simultaneously. I tried to use SDRAM as L1RAM is not sufficient for our purpose. Accordingly, I modified c6745.cmd file but is of no use. Can anyone suggest me where and what to edit to make use of SDRAM?
